Unity-DOTS-DynamicBufferHashSet

HashSet functionality for DynamicBuffer

Core idea

The main idea is to create two buffers, the first for storing user elements, and the second for implementing a hash set.

Two buffers are created. One directly for the user elements and the second one is to implement a hash set functionality. The buffer with user elements is fixed in size, but the buffer for the hash set is not. Thus, the second buffer goes beyond the size of the first one and allows you to create chains of elements with the same hash key.

How to use

Step 1

Add your dynamic buffer to entity

Step 2

Implement IEqualityComparer interface for your dynamic buffer element

Step 3

Add dynamic buffer to job system

Step 5

Init hash set buffer handler

Step 6

Use hash set functionality

Limitations

You can add only one hash set buffer per entity.
